There is no relationship at all between the Active Directory Name, the Mail
Domain, and the Web Domain. In fact the AD Domain should most definitately
be different. the only things they have in common is that you own all of
them and that "domain" starts with "D". You could use "ruytnsdt.fth" for
you Active Directory Domain Name and *@chicketsoup.org for the Mail Domain
and www.shortpeople.net for the Web Domain and everything would work fine.
Absolutely not. AD Domains have a single name. You can make it the same as
your Public one except for the ending and this would be both accepable that
considered the "normal" way to do it.
Public = mycompany.com
AD = mycompany.loc (loc = "local")
No. Those are not "logins" in a Windows AD Domain,...those are email
addresses,..the login would just be the "user". A login prompt for a
Windows Domain has three lines in the Prompt:
The Domain in the login is usually the netbios version of the name (single
word, no "dots"). But you can use the FQDN if you wish.
If you are dealing with a "two line prompt" that has no "Domain" entry, then
you prefix the username with the domain name:
